Documents can be inserted as attachments during message composition. Click the Attachments tab to upload your file.

Although the system allows you to upload attachments up to 2MB, this is very large and may be refused by the receiving server. We recommend you keep the file as small as possible (e.g. under 300KB and not exceeding 750KB). Smaller attachments are more likely to be delivered successfully.

If you can’t upload attachments, contact Support – they can enable attachments on your account if it’s available on your package.
